Thomson, June 3, 1902', i n' which a bal'l'or' lump of dough is first rolled between driven` rollers into athn sheet which is subsequently.

l pressure between a rotating drum' anda semicircular compression plate to kn'ead or work the doughinto proper condition for the pan.r Such machines usually include a loaf forming mechanism which-comprises a smooth roller arranged'beneath the lower part'ofthe" dough sheetingmechanism, and a'fluted roller arranged beneath the smooth roller and ad-ja-- cent the' drum, the lut'ed roller and' the smooth roller Cooperating to form the sheet r of dough/into a spiral roll which is deposited between the rotating drum'and the compression plate. It hasbeen found that when the spirally rolled l'oaf'is smaller'than normal,

it will remain vindefinitely between 'thelute'd 'i roller andthejsmooth roller and when it is thrown off the iuted roller it falls between the drum and the compression'I plate in a diagonal or endwiseposition so that the knead;

ing operation produces an imperfect loaf.v If the spiral roll is largerthan normal it will not remain Aupon the iuted roller long enoughl forV satisfactory curling or spiral rolling. One object of my invention is to providean adjustable apron upon the lutedroller lwhich is alsocommonly called the curler so that'the extent of the periphery of the luted roller r mechanism upon the different amounts of A of the rollers of' each'of Asaid pairs, in the exposed between the vedge of the apron and the'smooth rollercan be varied asvde'sired,A

to ensure properoperation of thecurling dough, and proper discharge oftheloaf.

Otherobjects are to provide an adjustable` curler apron'which includes a sheet of :metal and meansfor. moving it peripherally or circumferentially ofthe `fluted roller; to` proamounts of dough; to provide such mechanism which is simple and inexpensive Vin construction and can' be operated by an unskilled d person," 'and to obtainA other advantages and results 'as' may be `brought out by the follow`l ing description.'l f

"A-l'iopperQffis arranged above the uppermost sheeting',v rollfV ers 15, '16 to receive fa lfurnpf'o" ball-'vof dough iov a motor 1 by any suitable means in the di-lrections indicated by the arrows so as to force the dough between the rollers of each pair. The dough passing between the said.`

rollers is formed `into .a sheet andv then is operated upon bya curlingand loaf form# ing mechanism which spirally'rolls the sheet into a substantially cylindrical loaf. A guide plate 21 is mounted on the frame to bridge the space between the rollers 16 and 17 and guide the sheet from one pair of rollers to the other pair and a similar plate 22 is arranged between the lowermost sheeting roller 17 and the threadedroller 25 lof the loaf forming mechanism about Ato be described.

This loaf `forming mechanism includes a screw-threaded roller 25 arranged beneath the lower part of sheeting rollers17,v 18,

and a fluted roller 26 arranged beneath the theaded roller 25 and adjacent the drumB. The, rollers 25 and 26 of the loaf forming i mechanism andthe drum-B are driven inV the direction indicated by the arrows through suitable gearing notshownf v Y A compression plate ,F of sheet metal surrounds the lower half of the kneading drum B inrspaced relation thereto to form a channel between said drum and the, compression plate. The loaf Gr` formed by the curling roller 26 isdeposited--by action of gravityl over an apron IfIrinto the said channel and rolled with a squeezing pressure between the drum andthe compression plate to the opposite side ofthe drum wherebyrthe loaf is properly kneaded and worked intoa condition for baking.

AMy invention relates particularly apron H which is shown as comprising a plate 27 secured at its opposite ends to opposite sides 28 of the frame of the dough sheeting and loaf forming mechanism D, said plate extending parallel to the `fluted roller 26 and inuslightly spaced relation trie-reto. The surface of the plate 27 nearest the periphery of the roller 26 isformed withfa groove 29 in which is slidably mounted an adjustable apron plate 30V which is vshown as arcuate and substantially concentric with the roller 26. This apron plate 30 is movable circumferentially Yof the roller 26 byany suitablev means so thatthe amount of the periphery of the roller 26 betweenl the ledge 31 of said apron plate and the smooth roller 25 can be varied as desired. Such actuating means is shown as comprising a bar 32 having a forked end 33 slidably embracing a rod 34 extending transversely between the side pieces 28 of the frame D.A u'Ihe other end of the bar slidably rests uponthe top of the main fra-me A and has a returned extremity v35 to serve as an operating handle. The bar has a slot 36 through which passes a thumb screw 37 which to the is screw-threaded into the top of the main frame A and has an operating'knob 38 which upon rotation of the thumb screw serves to clamp the bar 32 between the main frame A and said knob. The bifurcated end of the bar is pivotally connectedV as at 39 to the lower edge of the apron plate'30. With this lconstruction it will be observed that by longitudinally moving the bar 32, the apron plate 30 may be .circumferentiallymoved with respect to the roller 261 andrthethumb screw 37 will hold the apron plate in adjusted position.` The apron plate isguided in its movements by cooperating of the groove 29 `in the plate 27 and the periphery of the roller 26. a v Y l In operation ofthe machine, when small amounts of dough are Vbeing formed into loaves the edge 31 of the apron plate is adjusted to a position close tothe threaded roller 25 as shown in Figure'l, while with larger quantitiesof doughytheedgef31 of the apron is moved farther-away from the threaded roller according to theY quantity of dough, as shown in Figurei. It is thus possible to ensure that the spirzallyv `rolledloaf G will be dischargedV or stripped from the roller v26 as soon vas it has been spirally rolled, and the loaf will be` so `discharged with its axis substantially parallel with the axis vof the drum B as is desirable. i j f' Y l/Vhile I have shown one specific form of adjustable curler apron and actuating mechanism therefor it will be understood that this is primarily for the purpose of illustrating the principles of the invention and'that many modifications and changes may bemade in the details of construction without departing from the spirit or scope thereof.

said guidegroove between said main plate and said first-mentioned jroller toward and from the second-mentioned roller and covering a .portion ofthe surface of said firstment-ioned roller, andmeans for moving said apron plate circumferentiallyof said firstmentioned roller.
